New, more precise measurements of a particle called the W boson are again suggesting that physicists\’ prized Higgs boson is lighter than previously predicted. Using detectors at the Fermi National Accelerator Laboratory in Illinois, Duke physicist Ashutosh Kotwal and his collaborators have made the world’s most precise mass measurement of the W boson, a key […] … learn more→

This week scientists at the Large Hadron Collider announced tantalising news about the biggest piece missing from the physics jigsaw. The Higgs boson is a hypothetical particle used to explain why many of the fundamental particles in the Standard Model of particle physics have mass. Proving if it exists is tricky because the model doesn\’t […] … learn more→
